F 3, n can body maybe advanced along the horn in the, conventional manner and is broughtinto a fiuxing station B at which the is applied.

The fluxins mechanism may be mount d, n a frame: 9 f ame. bracket Q seure to'the can body maker n proper positi n elativ t th fiuxin stationB. The. frame C carries a flux. pot D which contains a bath of liquidflux E'. A flux supply roller F is mounted for rotation in the flux not.preferably beneath the body maker horn A and on an axis. parallel to theaxis of the body maker horn. A flux applying roller G is preferablymounted above the 11-13 supply roller F a d, these two. roll rs aradapted for dual swin ing movement on a common pivotal mounting- H.

A roller shifting or actuating device I is used to move the rollers Fand into fluxing or nonl xin positi ns Provi sion is. made i'orascertaining if a can body b is in proper position at the fiuxingstation B and for this purpose a container body detector device J (Figs.2, 3 and 4) is preierably employed. This detector device is providedwith a latch element which operates in conjunction with the pivotalmounting H for the rollers so that in the event there is no can body 11in proper position for; fluxing, the detector device will lock the latchelement K thus preventing the normal movement of the rollers on theirpivotal mounting under the action of the roller shifting de- 7 vice I.

The body maker horn A for the can body '0 may be of the usual body makertype and is best shown in Figs. 3 and 6., For a cylindrical can body bthe horn is of cylindrical shape and the usual provision of advancingthe bodies intermittently along the horn may be used. For this purposethere is shown a pairo-f longitudinally extending grooves l l whichprovide slideways for reciprocating feed bars i2, these being .arrangedadjacent the top of the horn, in the usual manner. Feed dogs [3 of theusual type are carried in the feed bars and in this manner a can body I)is advanced into the fiuxing station B. In the embodiment of the presentinvention, the side seam a of the can body is disposed below the hornand for this purpose a clearance groove I4 is out in the horn to permitthe unobstructed advancement of the can body. v

The fluxing mechanism of the present invention is in the nature of anattachment and the frame C carrying the mechanism is secured to theframe of the body maker as required. The exact style of frame and itsmanner of attachment will depend upon the type of body maker being used.

The flux pot D best illustrated in Figs. 1, 3 and 4 preferably is shapedas a trough 2i and may 'be substantially semi-circular in cross section.Such a trough is formed with end members 22 and thus provides areservoirfor the liquid flux material E; The flux supply roller F is notattached to the flux pot but has freevertical movement. The end members22 may be notched out in clearance openings 23 for the roller shaft orother associated parts of the flux bracket 25 having a dovetail grooveor slot 26 formed in its upper portion. This construction.

allows for sliding removal of the flux pot for cleaning purposes. Thebracket 25 is formed with a depending projecting part 21' for mountingon the frame C of the flu'xingmechanism. A cap screw 28 may be used forsecuring the parts together. 7 I

The flux supply roller F is preferably of hollow construction to providea light weight roller 3|. This hollow cylinder is mounted on ahorizontally disposed shaft 32 which is carried in arms 33, 34 spaced onopposite ends of the roller. The arms 33, 3d are formed with hearingbosses 35, 36 in which the roller shaft 32 is journaled. These arms areintegral parts of a floating bracket or yoke member 31.

The-pivotal mounting H referred to comprises a sleeve 4| which in lengthis substantially equal to the width of the yoke 31. This sleeve providesfor a movable connection with the yoke which affords the floatingfeature referred to. For this purpose the sleeve M is formed with atrunnion boss 42 which is preferably slightly on center, as bestillustrated inFig. 5. The yoke member or bracket 31 is formed with anopening 413 into which the trunnion boss extends when the par-ts areassembled. The yoke loosely fits on the trunnion boss. A washer 45 and atrunnion screw 56, the latter being threaded into the :boss, retain theyoke 31in its floating position relative to the sleeve 6|. A setscrew41' (Figf3) 4 threaded into the sleeve presses against the trunnionscrew 46 and holds it in locked position.

The flux supply roller F and also the flux applying ro-ller G, areself-adjusting as to the fluxing operation. This is the direct result ofthe floating connection just described. The amount of floating movementis maintained within limits, the yoke 3? being formed with spacedprojections 48 (Fig. 5) along its bottom edge. These are disposed onopposite sides of the trunnion connection 42, 43 and each projectioncarries an upright limit pin 39. The sleeve ll is formed with spacedbosses 5i along its lower edge, each boss aligning with a correspondingprojection 48 on the yoke. Depending from a seat in each boss is a pin52 so arranged as to be in vertical axial alignment with a limit pin.The pair of pins 49, 52 on each side permits slight rocking movement ofthe yoke and parts carried thereby but limits such movement when a limitpin contacts its stop pin.

The sleeve at is keyed to a horizontally dis- .posed rock shaft 55 whichconstitutes an essential part ofthe pivotal mounting H previouslyreferred to. This shaft is held in fixed position in bearings 56, 51(Fig. 6). The bearing 58 is formed in the upper part of a bracket 53which is mounted on the frame C. In like manner the bearing 5? is formedon the upper part of a bracket 59 also mounted on the frame.

The flux applying roller G as shown in the drawings is mounted directlyabove the flux supply rolle-r F and is smaller in diameter. This rollerG is secured to a horizontal shaft 64 both shaft and roller beingparallel to the body maker born A and the flux supply roller F and itsshaft '32. The shaft 6| extends outwardly at both ends of the roller Gand is journaled in bearings formed at the forward ends of spaced links52, 53. The links 62, 63 are carried on a horizontally disposed rod 64which in turn is carried in spaced lugs 65, 66 which constitute anintegral part of the yoke 31.

As best illustrated in Fig. 1,. the link 62 extends on opposite sides ofthe lug and for this purpose is notched as at 61 to allow for slightmovement between the yoke 3'1 and the flux supplying roller supportingparts. This construction also prevents longitudinal shifting of one partrelative to the other. Thus it will be understood that the rod 64provides a connecting part between the supporting structures of the fluxsupply roller F and the flux applying roller G. The

rollers F and G as a result move together as a unit during the operationof the machine.

Adjustment is provided between these structures by utilizing a slightrocking movement between the parts on the rod 64 as an axis. By means ofthis adjustment the amount of contact or engagement or even a slightspacing between the rollers F and G may be obtained. While it is hereindescribed that the two rollers are in constant peripheral engagement, itwill be understood that this may include slight separation. In otherwords, by increasing the spacing between the rollers F and G a thickerfilm of flux will be transferred to the flux applying roller G andtherefrom to the side seam of the can.

Such adjustment of engagement is made for a given viscosity of flux andthereupon a uniform thickness of flux will be applied to the can bodies.

The arms 33, 34 of the yoke 31 are provided respectively'with topprojection pads 68 (Fig. 2) and 69 (Fig. 3). The respective links 62, 63of the flux applying roller G carry projecting bosses H, H (see alsoFigs. .1 and 6) The-bosses IL. F2 are disposed directly above the supplyroller pads 88, 69 and each boss threadedly supports an adjusting screw13. By' positionin the screw in its associated boss; the weight of theflux applying roller G and its associated parts issupportedon the arms33, 34 of the yoke and the desired spacing between the rollers F and Gas determined by this threaded adjustment gives the desired filmthickness.

In the foregoing description reference has been made to the unitarylifting of the rollers for applying the liquid flux to the side seam ao-f'the can body b after it comes to rest at the fluxing station and tolowering of the rollers to permit. an unrestrictedadvancement of thefluxed can body along the horn A and out of the flux-mg station. Duringboth raising and lowering of the rollers the flux snpplyroller F remainsin the liquid.- flux E of the flux pot D. Both rollers are constantlyrotated as will be described later and a proper supply of flux is:assured at all times;

Raising and lowering of the rollers F and G is brought about byoscillation of the shaft 55 (Figs. 3 and 6) by means of a cam action oithe actuating device I. At one end of the sleeve 4| a lever I5 (Figs. 1,3 and- 6) is formed with a bearing boss I6 which loosely surrounds theshaft 55. At the opposite end the lever 15 carries a pin 11 on which ismounted a cam roller 18. This cam roller is adapted to operate in a camgroove or track 19 formed in a face cam 8!. I

The actuation of the cam is timed fol, .synchronr ized action with theadvancement of can bodies 11 along the horn A and with the positioningof the bodies at the fiusing station for a fluiring operation.- Normallymovement of the lever 15 is transmitted to the shaft 55 to lift theflux. supply roller F and the flux applying roller G. A yieldabletransmission connection, however, from the lever '55 to the shaft 55provides for the nullifying of shaft movement in the absence of a canbody in proper position for flu'iiing; as will be hereinafter more fullydescribed in connection with the detector device J.

Adjacent the lever boss 16 the sleeve 41 is formed with an integralblock extension 82 which during normal operation of the machine moves inunison with the lever. The block 82 cohs'titutes a part of theyieldab'ls connection referred to and is formed with a lug 8-3 providinga seat for a bolt M having a retaining nut 85 threadedly mounted abovethe lug. The lever 15 is formed with a boss oreartib constituting a part(if the connection and this car is aligned with the lug 83. Ear i6 isapertured to receive the bolt 84. The 111 83 and the ear 3% normally arein the closed contacting position illustrated in Fig. 3. Bolt 84 extendsbelow the ear and is surrounded by a spring 8'3. At the bot-tom the bolt8% threaded'y carries lock nuts 38 by means of which the spring isproperly tensiohed. This provides a yielding connection Earth-e lever I5andthe block 82' of the sleeve 4!. As long as the machine is operatingnormally, that is with can bodies in proper position at the flw'r'ingstation, the fluxing operation continues and the cam-ill rocking thelever '15 also oscillates the shaft 55 and the par-"ts carried thereby.

The com 3! is mounted on a horizontally disposed driven shaft 9i '1, 3and 6) is jonrnaled in spaced bearings 92 formed in the frame C. ShaftQI is constantly rotated a drive shaft 93., For this purpose a. bevelgear 94 mounted on the sh'ait H" meshes with a hotel body ll'lQViilginto the fluxing station.

ear mounted on the drive shaft 93. 1 'Ifhe: drive shaft 9'3 may beiournaled in suitable bearings ee iorri'i'd in the frame (2 orthe-machine; The drive shaft 93 receives its rotation in any suitablemanner by means of which the proper actuaof the parts of the 'iluxingmechanism is obtained. Since such actuation is intime with the bodymaker of which the hem A is an 'essentiai feature; the hurtin mechanismwill be driven from the body maker. A proper driving connection from thebody maker may be afforded by means" of a chain drive 9? which operatesover a sprocket 98 mounted on the drive shaft 93.

The can body detector device 5, which it will be recalled, cooperateswith the latch element K arid the shifting device I for" moving therollers of? their pivotal. mountings'I-I, is best illustraed Figs. 2, 3and 6. This detector device compfises a longitudinal shoe HI whichextends alongside oi the horn 'A. Normally the forward end of the shoeIii is urged inwardly to rest within a longitudinal recess ii? cut inthe side or the horn A (Fig. 2) t The shoe Hi is connected by a shortarmH2 to a downwardly extending boss I- I3 which provides for the pivotalmounting of the shoe. I

Boss I it is loosely mounted onia vertically eiitending bolt we threadedinto the upper part of a bracket lug It? which forms an integral part ofthe bracket 55. When a can body h advances aiong the horn A into thefiUXlIlg station Bflthe forward end of the body engages the shoe HI androcks it on its pivotal connection H4 outwardly into sliding engagementwith the can The forward end of the shoe H l is formed with a projectingpart II! which extends along. the back or away from the body maker horn.This projection at all times engages the upper end of a finger II8 (seealso Figs. 3 and 7) which is urged toward the body maker born underspring tension. The finger H8 is an integral part of a bell crank I I9which i'sv mounted on the rod 64. An arm. I2I of the bell crank I I9 isat all times engaged by a spring I22v the upper end of which is seatedin a counterbore I23, formed in the rear face of the bell crank arm.

The opposite end of the spring 222 is seated in a counterboreI25-forrhed in a projecting shelf or lug I26 of a hub I21. The hub I21is secured to a stationary shaft I28. Shaft I28 isfheld in a bearingInformed on the bracket 58 and in a bearing I30 formed in the bracket 59just beneath the bracket lug H5. The hub I2 is extended into a si litclamping projection I32 (Fig. 6) and a cap screw I33 is used to clampthe arts togetlier so that the hub I21 at all times remainsstationarywith the stationary shaft I28. By rea son of this constructionthe finger 8- provides a constant. yielding pressure against the freeend of the shoe III.

A toggle link connection is provided between the bell crank H9 and thelatch element K. The 121 carries two upwardly extending lugs I35 whichare formed integral with the hub and which provide a bearing for ahorizontally disprised rock pin I36. A head I31 of the pin-I36 isoutwardly spaced from one of the lugs I35 sufiicientl-y to formsmounting for a pawl member 138 which constitutes the principal part ofthe latch element This pawl is clamped onto the rack I36 as at [39.

A split toggle sleeve or boss I45 is mounted on the rock 15in I36" inbetween the bearings proneed by the lugs I35 and is clamped onto the pinby a cap screw I46. By reason of this construction the pawl I38 moves inunison with the toggle boss I45 and with the rock pin I36 which formsthe connecting part for this cooperative movement.

The toggle boss I45 is formed with a depending part I41 which is slottedat I48 to provide a loose toggle connection with the bell crank H9. Thearm I2I of the bell crank is slotted at right angles to the slot I48 asat I5I to provide a seat for a toggle block I52. This toggle blockloosely and slidably fits within the slot I48 of the toggle boss partI41. The slotted arm I2I of the bell crank is formed with alignedtransverse bores I53 and after the block I52 is positioned'within theslot I5I of the bell crank a connecting locking pin I54 is passedthrough the openings I53 in the bell crank and through an opening I55 inthe block. Fig. 7 illustrates these parts in separated position prior toassembly.

It will be observed by reference to Fig. 3 that the can body b at thefluxing station B on the horn A has pushed back the shoe I I I and withit the finger II 8. This action rocks the rod 64 so that the bell crankH9 is moved in a clockwise direction against the resistance of thespring I22. By reason of the toggle link connection between the bellcrank II 9 and the toggle boss I45 just described, the rock pin I36 ismoved in a counterclockwise direction and the pawl I38 is lifted. Thisis the normal operating position, see also Fig. 6, and proper fluxingwill take place.

In the absence of a can body at the fiuxirlg station, the end of theshoe II I remains in the horn groove I I6. The spring I22, which it willbe'recalled is constantly pressing against the bell crank H9, yieldinglyholds the shoe in this position through the action of the finger H8.Fig. 2 illustrates this abnormal position of the parts. It is at thistime that the latch element K becomes effective, as will now bedescribed. r

The pawl I38 is formed with a hooked end I65 which, in the absence of acan body on the body maker horn, engages over a locking lug I66 formedon the block 82. This looks the block 82 against movement and holds theshaft 55, 'constituting the pivotal mounting H of the rollers F and G,against oscillation. This prevents movement of the rollers into fluxingposition throughout all cycles of operation until a can body b has beenbrought into proper fluxing position. The

roller shifting device I is actuated by the cam 8I and this cam movementtakes place irrespective of the presence or absence of a can body influxing position at the fluxing station B. When the block 82 isprevented from moving, the spring 81 yields to permit the normalmovement of the lever 15. At such time the ear86 separates from the lug83, as shown in Fig. 2. The flux applying roller G therefore does notmove up into position adjacent the horn A and accordingly flux is notuselessly applied to the horn in the absence of the can body.

Reference has been made to the fact that the rollers F and G areconstantly rotating and at a uniformly peripheral speed. This rotationis effected from the driven shaft 9|, as illustrated in Figs. 1, 4 and6. The shaft 9| carries a sprocket I over which operates a chain I16,this chain passing over a double sprocket I11 loosely mounted on theshaft 55. A collar I18 secured to the end of the shaft 55 retains thedouble sprocket I11 in operating position. An outer sprocket section I19preferably is anintegral part ofthe double sprocket I11, and azchain iiikeyed to the flux supply roller shaft 32.

mounted on the flux applying roller shaft 5|.

The pitch diameter of these gears I85, I 86 is such as to insure auniform peripheral speed of rotation of the rollers F and G.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing'from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.
